CRY3404-S01 Pressure-Field Microphone Set, 1/4", 0.56mV/Pa

CRY3404-S01 Pressure-Field Microphone Set, 1/4", 0.56mV/Pa

CRY3404-S01 is a 1/4-inch pressure-field prepolarized measurement microphone and preamplifier set designed specifically for high sound pressure level acoustic measurements.

The unique design of CRY3404-S01 allows it to perform acoustic testing in extremely high sound pressure environments, with the ability to withstand sound pressure levels up to 175 dB. It is particularly suitable for measuring sound characteristics in high-volume environments and evaluating and optimizing acoustic environments.

  • High-level pressure-field microphone set
  • TEDS microphone set
  • Extensive compatibility
  • Durable, reliable, and high-quality
